SOCIETY OF MODEL^AERONAUTICAL ENGINEERS
(London Aero-Models Association)
THE last outing of the members took place at Hendon,
when hydro-aeroplane trials were made on the Welsh Harp
under rather adverse conditions. Five machines put in an
appearance—Mr. D. A. Pavely's 4J lb. compressed-air
model and Mr. R. N. Bullock's rubber-driven fuselage sea-
plane (two floats only) being particularly fine pieces of work.
Mr. B. K. Johnson's spar tractor put up many good flights
from the water during the afternoon, as did also Mr. S. C.
Hersom's " Twin Pusher." Both Mr. Pavely and Mr. Bullock
got their machines to leave the water, but the somewhat gusty-
wind repeatedly caused a wing-tip to touch the water after
the floats had got clear, with the resulting inevitable " splash."
Consequently, no prolonged flights were obtained with these
two last-mentioned machines. Nevertheless, given a fair
day, they should undoubtedly put up a good performance.
On Tuesday evening, October 27, the first indoor meeting
will be held at Headquarters, Y.M.C.A., Tottenham Court
Road, W. 1, when a general discussion will take place on the
results of the competitions, records, etc., of the past year.
It is to be hoped that all members will make a special effort
to be present on this occasion, so that the Research Committee
may benefit by any suggestions for the coming year.
Will all members who are entering the Photographic
Competition be sure and send in photographs to Mr. B. K.
Johnson not later than November 1.

R.33 as Aircraft Carrier
THE R.33 airship made a short test flight on October 9
in the neighbourhood of Pulham. Several successful technical
tests were carried out, including a photographic record of
the motions of the ship taken from the ground.
On October 15 she was out again and made an interesting,
but by no means new, experiment at Pulham, when
an aeroplane was successfully launched from the airship
and afterwards, though not quite so successfully, the aeroplane
re-attached itself to the airship. Under ideal weather con-
ditions, the R.33, with a D.H.53 light aeroplane suspended on
a sort of trapeze gear beneath the airship's keel, left the
mooring-mast and proceeded to climb to an altitude of about
5,000 ft. Squadron-Leader Rollo Haig then climbed into
the pilot's cockpit and released the machine, diving earth-
wards until his engine got going. He then returned to the
airship for the purpose of " hooking " on. As he manoeuvred
the 'plane on to the clip, which secured the machine on the
trapeze," the airscrew came into contact with some wires
and broke. The machine made fast successfully, howevei,
and shortly after the pilot " let go " once again and glided
down to the aerodrome, the R.33 also descending and mooring
later to the mast.
Large Airship Shed for Karachi
THE Air Ministry have given a contract to the Armstrong
Construction Co., Ltd. (which is associated with Sir W. G.
Armstrong, Whitworth and Co., Ltd. , for the construction
of an airship shed at Karachi—for use in connection with
the proposed airship service to India. This shed will be
850 ft. long, 180 ft. wide and 170 ft. high.
" Bristol " Success in America
IN the light 'plane section of the New York Air Meeting,
the Powell Racer, a light 'plane designed and built by
Professor C. H. Powell, of Detroit University, won the speed
and efficiency race, and in fact, secured every first prize in
the competition, including the Aero Digest Cup. The Powell
machine is a very small affair, having a span of only 15 ft.
6 in. and weighing but 310 lb. The speed established was
76-4 m.p.h. The Powell Racer is fitted with a Bristol
" Cherub " engine, and the success of this British engine has
been widely noted and commented upon.

36 holes at Berkhamsted on October 11, and was won by the
Royal Air Force champion, Squadron Leader C. H. Hayward

Fatal Accident on Cross-Channel Air Line
FOG was the cause of an unfortunate accident to one of
the French Air Union " Goliaths " on October 16 whilst on
the trip from Paris to London, as a result of which one of the
passengers, Miss K. G. Burke, was killed and two others
were injured. The machine ran into a fog bank near Wad-
hurst, and the pilot, when attempting to land, collided with a
tree and crashed to the ground.
